Special Purpose Amplifiers

This Product Selection Guide contains information to help select products in the Special Purpose Amplifiers category on DigiKey.com

Special Purpose Amplifiers (linear amplifiers family) are used for processing analog signals. They contain integrated features such as voltage references, linear comparators, filters, or other non-amplifier functional elements in support of specific applications or application classes.


SelectionCharacteristics

Specifications to determine which Special Purpose Amplifier is right for your application.

Type: Indicates the intended function or a defining design feature of a device.

Applications: Application is the type of equipment or environment the device will be used in, they are tested and typically rated by a third party to ensure certain minimum standards for the application they are intended for. You could use one with a higher rating, but you cannot use one with a lower rating as it will fail in that application. For example, you could use a medically rated device to replace a commercial device, but you cannot replace the medical device with the commercial device.

Mounting Type: Indicates how the device is attached.

Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.

Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
